sounds right to me, im planning on only extending my bolt not my carrier. thread an exstension on to the bolt so i can use a captured spring return firing pin. a mauser barrel, and not sure what kind of gas block. id like to use a fal but they are getting scarce and i dont have one to spare so looks like a romi.

now to find the time to finish my romi builds and start on caliber conversions, ive been collecting parts for, .223, .308, 8mm, and 44mag

good luck!!!

I was only considering extending the carrier as well so that I could use the original recoil spring assembly. With the longer receiver length, I'll need to add carrier to keep the spring tension similar. There should be enough pressure from the 8mm to overcome the added carrier/bolt weight.

yes as discussed last year you need the longer coldsteel blank and readjust the templete to reflect the larger mag
when test firing use a commerical 8mm or reloads. not surplus
I would even donate a few reloads just to see if your build works
